Patented Apr. 26, 1932 UNITED STATES OSCAR WILLUMSEN, F OCEAN PARK,CALIFORNIA AIR VENT FOR DISPENSIZN'G CONTAINERS Application filedFebruary 11, 1930. serau No. 427,351.

Thepresent invention relates to dispensing containers and moreparticularlyto improve :ments in'reserve dispensing containers such asdisclosed in my allowed application Serial Number'300;810 allowedOctober 21, 1929.

The primary object ofthe present invenation isztoprovide a dispensingcontainer having a detachable nozzle normally concealed within thecontainer, with means for venting the container when the nozzle applied:to the-dischargeopening of the container.

A further object resides in the novel .arrangement-whereby the outer endof the air -venttube is closedby'the closure cap for the dischargeopening of the container.

A further object resides in the novel man ner in whichthe vent tube isdisposed within the container soastoprev-ent escape ofthe liquidthru'the vent tube while the contents are being dispensed thru thedischarge open- -in g of the container.

Astill'further objectresides in the-provision of an rimproved dispensingcontainer for oils, gasoline and the like having a pair 60fconcentrically arranged, spaced apart necks at its discharge'end, with avent tube opening to the atmosphere between the necks for venting thecontainer when the discharge nozzl'eis detachably connected with theinner- 'most' neck.

Other objects andadvantages of the invention will be apparent during thecourse of the following detailed description, taken in connection withthe accompanying drawings *forming a part of this specification and inwhich drawings r p Fi-gurel is aviewpart inlongitudinal section and-partin side'e levation of the improved container. 1

iii-the drawings, and wherein similar ref- 14 whereby the washer16 ofthe closurecap -erence characters designate corresponding parts thruoutthe several views, the reserve dispensing container or receptacleincludes a tubular body portion 5 being closed at its forward end by afront endwallfi and 'at its rear or opposite end by a rearend wall1'8.Each end wall 6 and 8 is preferably provided with an annular attachingflange 9 which maybe secured to the ends of the body portion 5 in anypreferred manner such as by soldering or the like. Secured intermediatethe ends of the body portion 5 is a'suitable handle 10 which extendslongitudinally of the body portion.

The rear end wall 8 supports a tubular .65- chamber forming member 11which projects axially into the body portion 5 and "the chamber formedby the member 11 isadapted to removablyreceive a-spout or nozzle 12adapted for detachable connection with the dis charge end of thecontainer. The -rneth0d and manner of mountingthis nozzle in'the chamber11 is clearly set forth in my allowed application above referred to. rThe end wall 8 is also adapted to receive the threaded cap '13 servingto retain the nozzle 12 in'thechamber 11.

Theend wall 6 at the forward or discharge end of the container isprovided with an axially disposed tubular threaded portion or .30

neck 14 for threaded reception of a closure cap 15. The closure cap 15is-threadedexteriorly upon the neck 14 and is preferably provided with asealingwasher 16 for sealing engagement with the outerend edge ofthe n8neck 14. Secured at its inner end to theend wall 6 inwardly oftheneck 14is a threaded sleeve or inner neck 18 which is-of less' externaldiameter than the internal diameter of the neck 14 forming. an annularpocket:19 between the concentrically arranged sleeves. This threadedsleeve 18 is secured'to-thewwall escape of liquid from the container.This threaded sleeve 18 forms the discharge opening ofthe container andpreferably has its outer end curled as at-21 and disposed flush with'theouter edge of the threaded portion will seat upon the outer end of eachof the necks 14 and 18. The end wall 6 preferably has an outturnedflange as at 22 in Figure 1 which extends into the annular pocket 19 toact as a spacer between the sleeve 14 and 18 and further aids inproperly connecting the sleeves to the end wall.

The tubular spout or nozzle 12 is preferably of flexible tubing and isprovided at its rear end with an enlarged internally threaded headportion 24 which is adapted for threaded connection with the externalthreads of the inner sleeve 18 after removal of the closure cap from itsthreaded connection with the outer sleeve 14. The outer or discharge endof the tubular flexible spout 12 is provided with an extrenally threadeddischarge cap 25 to which an extension or a reducing nozzle may beconnected for discharging the contents of the container into arelatively small opening, when desired.

As will be observed in Figure 3 the spacing between the necks 14 and 18is greater than the thickness of the spout head 24 so that threading ofthe head upon the inner neck does not close the annular pocket 19 to theatmosphere.

Referring now to the novel venting means for permitting ready and freeescape of the contents thru the nozzle 12, the same embodies a metal airvent tube extended thruout the length of the tubular body portion 5 withone end opening into the tubular body portion and its opposite endopening into the annular pocket 19. This air vent tube 30 has its outerend 31 extending with a sealed connection 32, formed by the solder 20,between the inner connected ends of the spaced necks 14 and 18 so thatthe tube opens into the annular pocket 19 in alignment longitudinally ofthe body portion 5 with the handle 10. Fromthe outer open end 31 of thetube 30 the tube extends upwardly along the inner surface of the frontend wall 6 as at 34 and is then extended in a straight line along theinner surface of the body portion 5 as at'35 with its open end 36 spacedslightly from the rear end wall 8. The tube portion extendslongitudinally of the body portion 5 directly beneath the handle 6 andin longitudinal alignment therewith, and may be secured to the bodyportion 5 in any preferred manner such as by soldering at the points 37.This extending of the portion 35 along the entire length of the bodyportion 5 and at the top side of the container when held by the handle10 for dispensing the contents of the container disposes the open end 36of the vent tube above the liquid contents of the container so that theliquid is not permitted to escape thru the vent tube while in the act ofemptying the container.

In conditioning the container for dispensing the liquid therefrom, thecap 13 may first beremoved andthe nozzle 12 removed from the chamber 11.The container may then be placed on end with the wall 6 uppermost andthe closure cap 15 removed so that the nozzle head 24 may be threadedupon the inner sleeve 18 as shown in Figures 2 and 3. The container maythen be held by the handle 10 and the nozzle 12 placed at the desiredlocation for delivering the contents of the container. On tilting thecontainer upwardly as shown in Figure 2, air will be drawn thru theannular pocket 19 into the outer end 31 of the vent tube 30 and permitsfree escape of the liquid thru the discharge spout 12.

When filling the container thru the opening formed by the inner sleeve18, a quantity of the liquid will enter the small vent tube 35 to thelevel of the liquid in the body portion 5, and thru handling of thecontainer a small quantity of the liquid may find its way into theannular pocket 19 which is ordinarily closed by the closure cap 15. Instanding the container on end for applying the nozzle 12, any liquid inthe pocket 19 will drain back int-o the container. When the container istilted for dispensing the contents, the liquid escaping thru the nozzle12 will create a suction in the small vent tube for drawing the smallcolumn of liquid therein into the body portion 5. The conical portion ofthe spout head 24 will have a tight fit with the inwardly curled outerend 21 of the tube 18 to prevent escape of the liquid at the jointbetween the head and sleeve.

Thus it will be seen that a novel arrangement has been disclosed wherebythe container may be vented from the discharge end without liability ofany of the liquid escaping thru the vent tube. It will also be apparentthat a novel arrangement has been shown whereby the single closure cap15 aside from sealing the discharge opening of the container also servesto close the outer end of the vent tube.
